1 / 12 page AME, Inc. 1 AME5106 Rev.A.01 PWM Control 2A Buck Converter C l Input voltage: 3.6V to 18V. l Output voltage: 0.8V to VCC. l Duty ratio: 0% to 100% PWM control l Oscillation frequency: 350KHz typ. l Soft-start, Current limit, Enable function l Thermal Shutdown function l Built-in internal SW P-channel MOS l SOP-8 Package l All AME’ s Lead Free Products Meet RoHS Standards AME5106 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control cir- cuit is able to vary the duty ratio linearly from 0 up to 100%. This converter also contains an error amplifier cir- cuit as well as a soft-start circuit that prevents overshoot at startup. An enable function, an over current protect func- tion and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 350KHz to 30KHz. Also, an internal compensation block is built in to minimum external com- ponent count. With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the SOP-8L mini-package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 18V, it is also suitable for the operation via an AC adapter. n General Description n Features n Applications S l PC Motherboard l LCD Monitor l Graphic Card l DVD-Video Player l Telecom Equipment l ADSL Modem l Printer and other Peripheral Equipment l Microprocessor core supply l Networking power supply |
